This will be a review over what you have learned this week'


Questions and Answers
  • 1. 

    How long does it take soil to form?

    • A.

      2-3 years

    • B.

      50 -100years

    Correct Answer
    B. 50 -100years
    Explanation
    Soil formation is a slow process that involves the weathering of rocks, the decomposition of organic matter, and the accumulation of minerals. It takes several decades to centuries for these processes to occur and for soil to develop. Therefore, the correct answer is 50-100 years.

    The heavier particles are?

    • A.

      On the top

    • B.

      On the bottom

    Correct Answer
    B. On the bottom
    Explanation
    Heavier particles tend to sink or settle down due to gravity, while lighter particles tend to float or remain on top. Therefore, the correct answer is "on the bottom" as heavier particles will be found at the lower part of a container or substance.

    Does every place in your community have the same type of soil?

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    The answer "no" suggests that every place in the community does not have the same type of soil. This implies that there is variation in soil types across different locations within the community. The presence of different soil types can have various implications for agriculture, construction, and other activities that depend on soil characteristics.

    Soil is classified by its?

    • A.

      Texture

    • B.

      Arms

    Correct Answer
    A. Texture
    Explanation
    Soil is classified by its texture, which refers to the relative proportions of sand, silt, and clay particles present in the soil. Texture affects important soil properties such as water-holding capacity, drainage, and nutrient availability. Sandy soils have larger particles and tend to drain quickly, while clay soils have smaller particles and hold water more effectively. Silt soils have medium-sized particles and have properties in between sandy and clay soils. Understanding soil texture is crucial for agricultural practices, as it helps determine the suitability of the soil for different crops and guides irrigation and fertilization strategies.

    Rate this question:

  • 5. 

    Soil particles can be?

    • A.

      Large or small

    • B.

      Large only

    Correct Answer
    A. Large or small
    Explanation
    Soil particles can vary in size, ranging from large to small. The size of soil particles influences important soil properties such as drainage, water holding capacity, and nutrient availability. Larger particles, such as sand, have larger spaces between them, allowing for good drainage but lower water holding capacity. Smaller particles, such as clay, have smaller spaces between them, leading to poor drainage but higher water holding capacity. Therefore, soil particles can be either large or small, depending on their composition and size distribution.
